3.

From 1 July 2012 roaming providers shall apply a euro-data tariff to all existing roaming customers automatically, with the exception of such roaming customers who have already made a choice of a specific roaming tariff, or who are already on a tariff which is demonstrably lower than the euro-data tariff or who have already made a choice of a package by virtue of which they benefit from a different tariff for regulated data roaming services than they would have been accorded in the absence of such choice.
